Hi i just built a new computer 2 days ago and it was working fine until i attempted to overclock it. When i overclocked it from 3.5ghz to 4.0ghz it woulded start so i reset the CMOS. After i booted up i saw very bad performance in games such as massive lag spikes which i was not seeing before. I downloaded something to look at my clockspeed and it said 1400mhz i thought it was a glitch so i got CPU-Z which also read 1400mhz. I also used OC genie 2 to overclock it again and got the same result 1400mhz. Here is my full parts list: Sapphire Radeon R9 270X 4Gb GDDR5, AMD FX 8320, Kingston Hyper X fury single stick 8gb, Sentey XPP 725w, MSI 970 gaming motherboard.
